Description
Drill Query Failing when selecting all columns from a Complex Nested Data File (Parquet) Set). There are differences in Schema among the files:
- The Parquet files exhibit differences both at the first level and within nested data types
- A select * will not cause an exception but using a limit clause will
- Note also this issue seems to happen only when multiple Drillbit minor fragments are involved (concurrency higher than one)
